Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen fuel cells, in particular to a connecting piece for hydrogenation of hydrogen fuel cells. Background Art

[0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is the reverse reaction of water electrolysis. Hydrogen and oxygen are supplied to the anode and cathode respectively. After hydrogen diffuses outward through the anode and reacts with the electrolyte, it releases electrons and reaches the cathode through an external load.

[0003] At present, in the process of hydrogenation of hydrogen fuel cells, hydrogenation connectors are usually used to connect the joints to facilitate the transportation of gas. In the process of hydrogen transportation, if the hydrogenation speed is too fast, the rapid compression of hydrogen can easily cause the temperature inside the gas cylinder to rise sharply. The excessively high temperature can damage the hydrogen cylinder material and even cause safety hazards. If the hydrogenation is too slow, the user experience will be seriously affected. The existing hydrogenation connectors do not have the function of flow regulation and are less practical. Therefore, in view of the above-mentioned deficiencies, the utility model makes the following improvements. Utility Model Content
